Musa is a 3D serious game that can be played through a real musical instrument. Our software recognizes played notes in real time, just through the microphone of user’s device. Targeted to kids, it runs on Android, iOS. We tested it with 3k families and we’re going to the market in April ‘19. The only way to pass challenges is to play the right notes on a real piano or keyboard. Kids learn without noticing thanks to a teaching method devised by music professors, joined with engaging game experience.
